Computer is running but power button has no effect. USB3 not working on left side of envy m7

envy m7
Microsoft Windows 10 (64-bit)

Power button will not start the laptop or shut it down. The two usb3 ports on the left side are dead. I start the computer by disconnecting all power and battery, then pressing power to drain then connecting external power and the fan will start followed by the computer booting.

This can be a very difficult problem to troubleshoot and correct.

 

If the PC ONLY starts when you hold the power button for a long time -- that is known as a Cold Start.  Win10 has a new hybrid sleep/hibernation setting that can cause problems both in starting and shutting down.

 

Win10 has enabled a new hibernation process known as Fast Startup -- which is enabled BY DEFAULT. This is different from Fast Boot, which is a BIOS/UEFI option.

Fast Startup is supposed to dramatically speed up the booting process, but in some PCs, it actually slows it down or causes it to hang. It's also a new form of hibernation known as hybrid sleep -- and this causes battery drain to maintain the state of the PC while turned off.

Disabling Fast Startup might fix the booting problem.

There are two ways to disable FastStartup in Win10: (1) through the Control Panel, and (2) through an elevated command prompt.

Control Panel - Open Control Panel --> Power Options.
Select "Choose what the power buttons do"
Select "Change settings that are currently unavailable"
At the bottom of the Window, under Shutdown settings, uncheck the box regarding fast startup

Elevated command prompt - run the following command:
REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Power" /V HiberbootEnabled /T REG_dWORD /D 0 /F

In both cases, reboot Windows.

NOW, FastStartup is disabled.

See if that helps.

The power has no effect. Not any effect at any time.

I didn't say anything about the power or changing it; I mentioned the Fast Startup setting -- and that has nothing to do with power settings.
